MEANS FOR TEMPORARILY ARRESTING THE MELTIN'G F ICE Application filed April 24,

My invention relates to means for temporarily arresting or retarding the melting of ice by providing holes in the same, by drilling or the like, and inserting in said holes a a refrigerant. By my invention the ice may be preserved for a predetermined time, when a fresh supply of the retarding material may be supplied and the ice be preserved for an indefinite time.

One of the objects of the invention is to enable ice to be kept in stores or other places without having the annoyance of the same melting; or, in other words it is kept in a dry state and may be easily handled. It may be also used where it is desired to have fanciful figures, such as animals for advertising,

entertainments, or similar places.

In the drawings forming a part, of this specification, and in which like symbols of W reference represent corresponding parts in the several views Figure 1 is an elevation of a cake of ice, showing four holes with the refrigerant in the same;

Figure 2 is a sectional view, showing a cylinder containing the refrigerant in the same;

Figure 3 is an end view of the cylinder of paper, or the like, and the refrigerant in the same;

Figure 4. is a longitudinal view of the cylinder in its wrapped state; and,

Figure 5 is a longitudinal section of a fish, to illustrate one feature of the same.

In the drawings the numeral 1 illustrates a cake of ice with the refrigerant in the same, The refrigerant 2 is preferably solidified carbon dioxide, or the like, and is in closedin a paper wrapper 3; and 4: are the A, holesdrilled in the ice. In Figure 5 I have shown a fish with the refrigerant in the same. v

The solidified carbon dioxide is placed in a porous cylinder of paper or the like by any well known means, preferably wrapped similar to a cigarette, and the wrapper being moist the refrigerant and the same become as a solidpiece. When the refrigerant has wasted away a new supply may be placed in the article and melting prevented. The

reason for the use of the wrapper is for convenience in inserting the refrigerant and for withdrawing the same when it has served the purpose of preserving the ice. When a figure has extensions such as arms and legs, the r holes should be in the same; and the holes 0 would naturally vary both in area and number according to the size of the cake of ice or figure that is to be preserved. Of course the keeping time depends upon the amount 6 of dry carbon dioxide thus physically and mechanically introduced into the body of the ice. The wrapper used in the invention is kept in shape by reason of the same being previously dampened and naturally freezing as the carbon dioxide is encircled.

The cylinders should of course approximate the size of the holes in the ice.

Having now fully described my invention, what I claim as new, and desire to secure by Letters-Patent, is

1. A cake of ice or the like formed with cavities, a solidified refrigerant having a lower freezing point than ice to be received in said cavities, and a wrapper for the refrigerant.

2. A refrigerant, consisting of a block of ice having embedded therein a body of solid carbon dioxide.

3. A cake of ice or the like formed with holes in the same, a solidified refrigerant adapted to be received in said holes, and a porous wrapper for the refrigerant, said refrigerant and wrapper approximating the size of the holes.

Inftestimony whereof I aflix my signature.
